Summary of the invention
The purpose of this utility model is the problems referred to above overcoming prior art existence, provides a kind of coiled tubing to spray and creeps into casing sidetracking rotation cloth hole guider.The utility model coordinates with continuous oil pipe tool pipe string makes it possess turning function, is undertaken being windowed by Vertical dimension horizontal drilling by coordinating coiled tubing.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of coiled tubing sprays and creeps into casing sidetracking rotation cloth hole guider, comprise guider body, it is characterized in that: described guider body diameter is less than operation casing inner diameter, guider body upper end is the link be connected with steering gear, lower end is the link be connected with guide shoe, be provided with the guide rail of through guider body in guider body, guide rail comprises tilting section, vertical section, the section of turning to and horizontal segment from top to bottom successively.
The isometrical setting of described tilting section, vertical section, the section of turning to and horizontal segment.
Described guider body turns to slotware to form by two levels, and two levels turn to slotware bolt to be fixedly connected to form guider body.
Described level turns to slotware is provided with and turns to groove, and after two levels turn to slotware to be fixedly connected with, two turn to groove to be combined to form guide rail.
Described two levels turn to slotware to be connected by each a pair of upper and lower two ends, middle single three bolt fixed locks.
Employing the utility model has the advantage of:
1, the utility model coordinates with continuous oil pipe tool pipe string and makes it possess turning function, undertaken being windowed by Vertical dimension horizontal drilling by coordinating coiled tubing, after going out sleeve pipe by coiled tubing window sidetracking, high-pressure injection method is utilized to get out the dark radial hole of multiple about 100m, significantly to increase drainage area, to increase oil and gas production.
2, the utility model simple operation, due to this guider need to connect with oil pipe steering gear with the use of, by the simple operations of put-on and delegated oil pipe, realize guider direction and change, thus drive guider and steering gear to rotate simultaneously, the bore operation of intended orientation.
3, the utility model use safety, guider upper end connects steering gear, lower end connects guide shoe instrument, as long as before guaranteeing well, two pieces of levels turn to slotware tightly to be locked by bolt, guarantee that oil pipe and steering gear, steering gear and guider are connected firmly, be not just subject to other External force interferences after entering well, working security is high.
4, the utility model improves the effect that coiled tubing is holed to sleeve pipe, be applicable to the cased bore-bole before coiled tubing radial water perforation stream radial direction well, coordinate radial direction well technique significantly to improve and singly enter output, reduce marginal well development cost, will be widely used in old well production potential tapping.
5, the utility model structure is simple, cost is lower, easy to use, for coiled tubing technology provides a kind of possibility, coordinate coiled tubing technique can greatly improve Oil/gas Well reservoir reconstruction effect, greatly improve the circulation of petroleum gas in reservoir, increase Oil/gas Well well yield.
